摘要
立筒仓粮堆属于深粮层,仓内的害虫分布形式有整仓随机分布型,表层、上层和底层分布型,以及局部分布型。对于不同的分布形式可分别采用整仓环流熏蒸,仓顶、仓底投药熏蒸和局部熏蒸。筒仓的害虫防治也应该贯彻“以防为主,综合防治”的方针,发生害虫时要及时治理,无虫时要预防害虫的感染。
The grain mass is deep in a silo, and the insects can randomly distribute throughout the whole storehouse, or only occur at the surface, upper and bottom, or arises at local grain mass. Therefore, according to different insect distribution patterns, whole storehouse circulation fumigation, applying the pesticides at the top, upper and bottom of grain mass, or local fumigation can be choosed to effectively control the insects. The principle, priority to prevention and integrated management, should be carried out to control the insects in silos. Effective measures should be timely taken whenever insect happening, and preventing insect infection should be implemented before insect happening.
